International Journal of Mechanical Sciences (2024). [2] Study of an arc-shaped high-sensitivity transducer based on tangentially polarized series connection. Measurement (2025).

In one study, a z-structured piezoelectric transducer was developed to achieve a low-frequency, compact design by utilising a bender beam that couples longitudinal and bending vibrations—a ...

The traditional form of cymbal transducer is composed of cymbal endcaps bonded to a piezoelectric ceramic, whose radial vibrations drive relatively high amplitude endcap displacements. This transducer ...

This paper presents an impact-induced frequency up-conversion piezoelectric energy harvester (FUC-PEH) to improve low-frequency output performance. The FUC-PEH includes a high-frequency piezoelectric ...

Now, researchers publishing in ACS Sensors report a toothbrush-shaped ultrasound transducer that can provide a less invasive screening for gum disease.

The results support the reliability of the toothbrush-shaped transducer as a less invasive technique for monitoring gum health. Credit: Adapted from ACS Sensors 2025, DOI: 10.1021/acssensors.5c00521 ...

When visiting the dentist, you might remember being poked and prodded by a thin metal instrument to check your teeth and gums. This technique, called periodontal probing, is used to look for signs of ...
